UNITED ARGYLE CAMPBELL, OE CHICAGO, ILLINOIS, A'ssIGNOE rro ENTERPRISE RAILWAYv EQUIPMENT COMPANY, OP, CHICAGO, ILLINOIS.

ICAEL T0 all 'whom z'zfimay. concern:

Be it'known that I, ARGYLE CAMPBELL,

a citizen of the United States, residing at Chicago, in the county of Cook and State-v of Illinois, have invented a certain new and useful Improvement in Cars, of which the following is a full, clear, concise, and exact description, reference being hadto thev accompanyingy drawings, forming a part of this specification.

This invention relates to improvements in cars. i One Object of the invention is to a freight car of the box type especially adapted for the carrying of grain or other bulk material adapted to be discharged I through a hopper.

Anothe1object of the'invention is to provide a car havinghopper door mechanism of a novel and highly eilicient and easilyoperable type. l' y Still another Vobject of the invention is to provide a hopper car adapt-ed for the carrying of grain and like materials wherein an eiclent' grain. seal is formed around the door closure.

The invention furthermore consists in the improvements in the parts 4and devices and in the novel combinations of 'the parts and devices A hereinn shown, described and made the subject matter of claim.

' In the drawingsv forming a part of this specification, Figure 1 is a side elevation of approximately one-half of a car embodying my improvements. Fig. 2 is an end. elevational Aview of the improved car. Fig. 3 is -a'vertic'al'transverse sectional view taken through .the body bolsterand illustrating one-half ofthe car, the section being upon a larger scale than the end elevation shown in Fig. 2. Fig. 4 is an enlarged detail sectional view taken through one of the hoppers and more clearly illustratesl the-hopper proximately Online 5545 of Fig. 4. And

Fig. 6 is a plan floor view of a section of approximately one-half of the car to illustrate the arrangement of hop Ders.

In said-drawings, the car ody is vshown I as made entirely of metal and has sheet metal sidewalls 10--10, sheet metal end provide Specification of Letters Patent. Patented June 1, '1920. Application filed May 19, 1919.` Serial No. 2v8,181.. n i' I i walls 1l-1l, asheet vmetal ro f 12, channel center'sills 13-13shaving a co Ter plate 14 and ridge-shaped diverting boards 15 v'exthe latter being-located between transverse sets of hoppers, as clearly .illustrated in `Figs. 1 and It will be noted that the car which I have chosento illustrate my invention differs from .the usual boxcar'in'that my invention, the grain or other bulk material will preferably-'be introduced at the top ofthe car-vas, for instance, through the opening v.or hatch indicated diagrammatica-lly at 18 in the roof of the car in Fig. 1. As indicated by Figs. 1 and 6, the car is preferably provided with eight hoppers, four on each side of the.center sill extending lengthwise-of the car. lFlach of these hoppers differsfrom the ordinary construeltionof hoppers in thatthere is a' true hopper section proper and 'belowthe hopper it has no side or end doors, but, in fact, is`v closed on all sides thereof. In carrying'out section proper what may .'be termed a discharge mouth. Each of said hoppers `is formed by oppositely and downwardly n-f clined end hopper sheets -19-19, an outer inlwardly and downwardly inclined -hopper sheet 20 and an inner downwardly and 'outwardly inclined hopper sheet 21. The' end hopper sheets of the hoppers nearest the end of. the oar form a. continuation of what `may be termed the inclinedv ,floor 22 of the car, as showny in Fig. 1,

said Hoor being extended to theend wall 11 and united therewith, as will be understood.

The other end hopper sheets i9 of the. hoppers are extended up to, and united with,

.vertical partitions 23 in the car which ex-- tend from the side thereof. These :partitions V'extend upwardlyl a greater part of the height of the car, but not to the rooflthereof, as shown in Fig.'1. The outer hopper sheets 20 extend up to the sidewalls 10 ofthe car and are united.thereto, and the inner hopper sheets 21 are extended up to the center sills and .united to the latter. As-

verging.

The discharge mouth of each ho per is formed by continuing the outer opper sheet downwardly, as indicatedat until the lower edge thereof is approxr mately in the plane, extended, of theinner' hoppersheet 2l. The sides of the discharge mouth are formed by .vertically extending substantially triangular sheets .Q5-25, se-

cured, at their upper edges, to the lower edges of the end hopper sheets 19. Aswill vide a seal to prevent leakage of grain and other similar bulk material while the car is in' transit. To accomplish this result, I have provided a novel arrangement as follows: surrounding the door openingabove mentioned, is a casting 26 having 'a suitablev flange adapted to' be riveted to the outer sides of the hopper sheet 20, end hop er sheets 19, vertical sheets 25 andthe unt erside of the inner hopper sheet Ql-said flange being indicated at 27. Said casting is extended beyond the openingproper and alo is provided on three sides of the opening with an outwardly flaring fiange 28, the inner surfaces thereof, onvsaid three sides, being flat, as evinced fro1n an inspection of Fig.- 4. Along the upper horizontal edge of the door opening, said casting 2G is provided with a convex iangey 2SA-and also -with suitable, hinge lugs 30-30. The coperatin'g door indicated by they reference 31 is also preferably in the form of a 'casting and on three sides thereof is provided with beveled or inclined flanges 32 Aco'perable with theflaring flanges 28 of' the casting 2G. Along its upper horizontal edge the door 3l is provided with a concave flange 33 coperable with the convex flange 29 of the casting 26. The convex fiange 29'and concave flange 33 are struck on radii, the center of which coin-` cides with the pivotal axis 34 of the hinges for the door, it being understood that the door 31 has suitable hinge Ilugs 35 adapted to be connected to the corresponding hinge lugs 30 by a pin or other suitable connection. From the foregoing description, it will be evident that las the door is movedvto closed position, it will be wedged on three sides by the inclined flanges and a seal 'will always be maintained in any position of theA door along the upper edge by ineansof thecurved flanges 29 and 33; i This arrangemean provides a cheap construction, easily manufactured and applied.

For operating the doors, l preferably provide two duplicate sets o f mechanisms so that four doors are operated at a time.. lfm asmuch as these mechanisms are both alike, it will only be necessary to describe one of them in detail` Referring partcuiariy 37-37, united at. their lower ends 4sheave wheels Figs. 4 and, it will be seen thatlthe'meclia;

nism for each set of hopper doors comprises plates 36, to which in turnare secured longitudinally spaced sets of depending plates by a U-shapedvplate 38. The depending Vertical 'plates 37.are slotted, as indicatedat 39,

within which slots are adapted to slide, up and down', pins 40. Each pin 4() is carried by a pairof short links 4l which are piv oted, as indicated at '42, toa lever arm 43 rigid with a longitudinally extending shaft 44. rl'he shaft 44 is mounted in suitable bearing brackets 45 that are attached to suitable cross plates on the under sides of connected, as indicated at 150, to the corresponding door 3l.

For rotating each shaft 44, I provide a transversely extending operating shaft 50.

Said shaft 50 is mounted in a suitable bearing 51. at its outer end',,a"s indicated in Fig. 4, and is extended through the nearest center sillll and'has its inner end seated in a bearing 52 carried by the inner face of the remote center sill 13. Said operating shaft 50 may be provided with anyT suitable form of pawl oi' ratchet mechanism and locking deyvice at .its outer end, the same being indicated at 53 in Fig...4. f Mounted on the shaft 50 are two sheave wheels and 55, one being on the outer side of the center sill and the other on the inner side thereof` as clearly illustrated in Fig. 4. From the sheave wheels 54 and 55 run chains 56 to a corresponding pair of sheave Wheels 57 and 58 carried by the longitudinal shaft 44, the

y sheave wheels 57 and 58 being, of course, in

planes at right angles to the planes of the 54 and They are arranged, however, so that linescan be drawn tangential to the surfaces of the corresponding sets of shea ve wheels,U as will .be clear from an inspection of Figs. and 5. (lne of said chains 56 is used when the shaft 44 is. to be rotated in 'one direction and the other chain comes into play when said shaft 44 is rotated in the opposite direction.- As will be obvious, rotation of the shaft 44, as viewedin Fig. 4in a counter-clockwise directionwill elevate the lever arm 43 and'break orcollapse the strut between the opposed sets of doors 3l and permit the latter to open.`

Although l have herein shown and described what l 'new consider the preferred same is merely illustrative and I contem-v' 'ter sills ,and extending through one of them,

manner of carrying out the invention, the

plate all changes and modications that come within the scope of the claims appended hereto.

`I claim: I l

1. In a car of the character described, having hopper's on opposite sides of the'center sills provided with center dumping hopper doors disposed in transverse alinement, the combination with a transversely extending operating shaft disposed between'pairsof hoppers, said shaft be'ing mounted at its inner end in bearings carried by the center sills and extending through one of the, center sills, of sheave wheels' carried by said shaft,`

' one being located outside of a center sill and the other on 4the inner side thereof, a longitudinally extending operating shaft disposed below the transverse` shaft and having a pair of sheave wheels thereon, flexible connections extending between said 'sheave wheels, said longitudinally extending shaft being disposed beneath the center sill through whichthe transverse shaft is eX- tended, and 'link connections from said longitudinally extending shaft to the sets of hopper doors for operating the'latter simultaneously. I y i 2. A. car of the character described having .a plurality of hoppers. on oppositel sides of the center sills and arrangedin pairs transfo'rv each of said openings, the doors being pivotally mounted alongv their upper edges to swing about axes parallel with the center sills .and below the latter, of'mechanism for y operating said doors, said mechanism including, a transversely 4extending operating shaft ]ournaled at lts inner end on the censheave wheels mounted on said shaft, one between the center sills and the other outside thereof, a longitudinally extending shaft flexible connections between said` a plurality of hoppers'in the bottom thereof, i

each hopper beinglformed by two'end oppovsitely and downwardly inclined hopper sheets, an outer hopper sheet extending downwardly and inwardly from the side wall of the car, and an inner hopper sheet extending outwardly and downwardly from the center sill, whereby all four sides of each hopper converge to a point below the center sills and car side; each hopper having also a discharge mouth at the bottom thereof composed of a continuation of said outer hopper sheet and two additional substantially I triangular lsheets extending transversely of the car and secured to the respective lower edges of said end hopper sheets, eachy discharge mouth having av rectangular disharge opening facing toward the center of t e car; a pivotally mounted door for each of said openings; and mechanism for operating the doors. f
